Access:
• DMA_x: DMA Channel x Interrupt
This bit is set when an interrupt is triggered by the DMA channel x. This triggers a USB interrupt if DMA_x is one.
This bit is cleared when the UOTGHS_DEVDMASTATUSx interrupt source is cleared.
• PEP_x: Endpoint x Interrupt
This bit is set when an interrupt is triggered by the endpoint x (UOTGHS_DEVEPTISRx, UOTGHS_DEVEPTIMRx). This
triggers a USB interrupt if UOTGHS_DEVIMR.PEP_x is one.
This bit is cleared when the interrupt source is serviced.
• UPRSM: Upstream Resume Interrupt
This bit is set when the UOTGHS sends a resume signal called “Upstream Resume”. This triggers a USB interrupt if
UOTGHS_DEVIMR.UPRSME is one.
This bit is cleared when the UOTGHS_DEVICR.UPRSMC bit is written to one to acknowledge the interrupt (USB clock
inputs must be enabled before).
• EORSM: End of Resume Interrupt
This bit is set when the UOTGHS detects a valid “End of Resume” signal initiated by the host. This triggers a USB interrupt
if UOTGHS_DEVIMR.EORSME is one.
This bit is cleared when the UOTGHS_DEVICR.EORSMC bit is written to one to acknowledge the interrupt.
• WAKEUP: Wake-Up Interrupt
This bit is set when the UOTGHS is reactivated by a filtered non-idle signal from the lines (not by an upstream resume).
This triggers an interrupt if UOTGHS_DEVIMR.WAKEUPE is one.
This bit is cleared when the UOTGHS_DEVICR.WAKEUPC bit is written to one to acknowledge the interrupt (USB clock
inputs must be enabled before).
This bit is cleared when the Suspend (SUSP) interrupt bit is set.
This interrupt is generated even if the clock is frozen by the UOTGHS_CTRL.FRZCLK bit.
• EORST: End of Reset Interrupt
This bit is set when a USB “End of Reset” has been detected. This triggers a USB interrupt if UOTGHS_DEVIMR.EORSTE
is one.
